CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Patent application Ser. No. 61/588,452, filed Jan. 19, 2012, which is herein incorporated by reference in its entirety.

BACKGROUND

The field of the disclosure relates generally to fire-fighting systems, and more specifically, to methods and systems for use in controlling fluid flow.

Fire-fighting devices (e.g., pumper trucks) are used to fight fires by pumping fluid (e.g., water, foam, or another flame retardant) from a source through hose lines wherein the liquid may be directed, i.e., sprayed, on a fire to facilitate the extinguishing or containing the fire. Known pumper trucks include controls to regulate the operation of the truck and to control the flow of liquid from the truck into the hose lines. Such controls generally include a plurality of valves used to control the flow of liquid to a fire pump from a storage tank transported onboard the truck or from another liquid supply source (e.g., a fire hydrant). Such valves also enable control of the flow of liquid from the fire pump to fire hoses or other discharge devices. Known controls include pressure and flow rate gauges used to monitor the pressure and flow rate of liquid at various locations within the pumper truck. For example, pressure gauges may monitor the pressure of the liquid received by the fire pump from the supply source. Generally the pumper truck controls used to regulate the valves and the fire pump, as well as the pressure and flow rate gauges, are commonly positioned in a control panel on the side of the pumper truck.

In known pumper trucks, during use, an operator, typically referred to as an engineer, must manually operate the controls of the pumper truck. More specifically, the engineer manually manipulates the controls to alter the flow rate and/or to control the pressure of liquid output by the pumper truck to a hose. Moreover, during operation, a firefighter positioned near a nozzle of the hose coupled to the pumper truck verbally communicates to the engineer (typically via a hand-held radio) any desired changes in the flow rate and/or pressure of liquid delivered through the hose to the nozzle. In response, the engineer manually adjusts the controls to enable the desired change in the flow rate and/or pressure of liquid delivered through the hose to be achieved. It is common for one engineer to be responsible for monitoring and responding to communications from multiple firefighters that each have a separate hose coupled to the same pumper truck. Moreover, the same engineer may also be responsible for acting as a spotter and/or controlling the operations of a mechanized fire ladder.

Accordingly, known control systems rely on the engineer to translate and execute orders communicated by a firefighter, and in response, to manipulate the controls of the pumper truck. The reliance on the engineer increases both the cost of operations and introduces the possibility of human error, as the engineer must listen to and understand verbal commands that may be difficult to understand and/or interpret depending on the location of the firefighter, the location of the fire, and/or other factors including environmental factors.

DETAILED DESCRIPTION

The present disclosure relates to fire-fighting systems, and more specifically, to methods and systems for use in controlling fluid flow. In one embodiment, a hose appliance includes an inlet that is removably coupleable to a first hose and/or a first hose appliance, an outlet that is removably coupleable to a second hose and/or to a second hose appliance, a body that extends between the inlet and the outlet, and a control module that includes a transceiver that receives data from the fire-fighting device and that transmits data to the fire-fighting device to facilitate controlling the fire-fighting device.

As used herein, an element or step recited in the singular and preceded with the word “a” or “an” should be understood as not excluding plural elements or steps unless such exclusion is explicitly recited. Moreover, references to “one implementation” or “some implementations” are not intended to be interpreted as excluding the existence of additional implementations that also incorporate the recited features.

FIG. 1 is a perspective view of a first exemplary embodiment 130 of a hose appliance 100 that may be used with a fire-fighting device (e.g., a fire truck) at a location remote from hose appliance 100. FIG. 2 is a perspective view of a second exemplary embodiment 140 of hose appliance 100. As used herein, a hose appliance is a tool used by firefighters to direct or control fluid flow and is positioned between a fluid source (e.g., a pump and/or a hydrant) and a fluid destination (e.g., a nozzle).

In the exemplary embodiment, hose appliance 100 includes at least one inlet 150 that is removably coupleable to a hose and/or another hose appliance, at least one outlet 160 that is removably coupleable to a hose and/or another hose appliance (not shown), and a body 170 extending between inlet 150 and outlet 160. As shown in FIG. 1, hose appliance 100 is a coupling that includes one inlet 150 and one outlet 160. As shown in FIG. 2, hose appliance 100 is a gated wye that includes one inlet 150 and a plurality of outlets 160. In the exemplary embodiment, the gated wye includes at least one gate (not shown) for controlling water flow through outlets 160. The gate may be actuated automatically or manually.

Hose appliance 100 may include any number of inlets 150 and/or outlets 160 that enables hose appliance 100 to function as described herein. Inlet 150 and/or outlet 160 may also be of any size to fit any hose diameter, and/or inlet 150 and/or outlet 160 may be mismatched in size to be either a reducing coupling or an enlarging coupling. Any hose appliance mentioned as a hose appliance, a coupling, and/or a gated wye is interchangeable with any hose appliance in the fire service used to connect hose or other hose appliances on a fire scene to the fire-fighting device.

FIG. 3 is a perspective view of an exemplary nozzle 180 that may be used with the fire-fighting device and/or hose appliance 100. In the exemplary embodiment, nozzle 180 includes inlet 150 removably coupleable to a hose and/or hose appliance 100, an outlet 190 configured to discharge fluid, and body 170 extending between inlet 150 and outlet 190. In the exemplary embodiment, inlet 150 and/or body 170 of nozzle 180 may be substantially similar to inlet 150 and/or body 170 of hose appliance 100. In the exemplary embodiment, outlet 190 includes a mechanism that enables nozzle 180 to discharge fluid therefrom in a desired manner (e.g., a stream, a cloud, a mist). That is, outlet 190 is configured to control and/or modify a direction and/or a characteristic of fluid flow (e.g., flow rate, speed, direction, mass, shape, and/or pressure) as it is discharged from nozzle 180.

In the exemplary embodiment, inlet 150 includes a first connector (e.g., a threaded inner surface removably coupleable to a hose and/or another hose appliance having a threaded outer surface) (not shown), and outlet 160 includes a second connector (e.g., a threaded outer surface 200 removably coupleable to a hose and/or another hose appliance having a threaded inner surface). Alternatively, inlet 150 and/or outlet 160 may include any other coupling mechanism that enables inlet 150 and/or outlet 160 to be coupled to a hose and/or another hose appliance.

In the exemplary embodiment, hose appliance 100 and/or nozzle 180 includes a control module 210 operable to wirelessly communicate with the fire-fighting device. In the exemplary embodiment, control module 210 includes a transceiver (not shown) configured to receive data from the fire-fighting device and to transmit data to the fire-fighting device to facilitate controlling the fire-fighting device. For example, in the exemplary embodiment, data transmitted to the fire-fighting device facilitates opening and/or closing a valve, increasing and/or decreasing a fluid pressure, and/or increasing and/or decreasing a flow rate based on user input.

In the exemplary embodiment, a display module 230 is configured to provide information to the user. In the exemplary embodiment, display module 230 is coupled to control module 210 and includes a tank level indicator 240. In the exemplary embodiment, tank level indicator 240 includes a plurality of lights and is configured to illuminate the lights based on a fluid supply associated with hose appliance 100 and/or nozzle 180. For example, when hose appliance 100 and/or nozzle 180 is coupled to a tank (not shown), tank level indicator 240 illuminates a number of lights that correspond to a volume of fluid stored within the tank (e.g., a full tank is indicated by illuminating all of the lights, a half tank is indicated by illuminating half of the lights, and an empty tank is indicated by illuminating none of the lights). When hose appliance 100 and/or nozzle 180 is coupled to a continuous fluid supply (e.g., a hydrant) (not shown), tank level indicator 240 is a continuous fluid source indicator and illuminates the lights different from when the hose appliance 100 and/or nozzle 180 is coupled to the tank. For example, tank level indicator 240 may illuminate the lights in a different color and/or blink and/or pulse in a predetermined pattern. Alternatively, tank level indicator 240 may illuminate the lights in any pattern and/or color that enables tank level indicator 240 to function as described herein.

In the exemplary embodiment, display module 230 includes a pressure setting indicator 250 that includes a plurality of lights and configured to illuminate the lights based on an amount of fluid requested through hose appliance 100 and/or nozzle 180. For example, pressure setting indicator 250 displays numbers that correspond to a fluid pressure requested at and/or through hose appliance 100 and/or nozzle 180. In the exemplary embodiment, a collar 260 circumscribing at least a portion of body 170 is rotatable about body 170 to adjust the fluid pressure requested at and/or through hose appliance 100 and/or nozzle 180. For example, collar 260 may be rotated in a first direction (e.g., a counterclockwise direction) to request an increase in fluid pressure and/or at least partially open a valve, and in a second direction (e.g., a clockwise direction) to request a decrease in fluid pressure and/or at least partially close the valve.

In the exemplary embodiment, collar 260 is translatable along body 170 between a locked position and an unlocked position. In the locked position, collar 260 is restricted from rotating about body 170, and, in the unlocked position, collar 260 is free to rotate about body 170. In at least some embodiments, collar 260 is biased in the locked position. Hose appliance 100 and/or nozzle 180 may include any mechanism that enables a fluid pressure to be adjusted as described herein including, without limitation, a button, a dial, a slide, and the like.

In the exemplary embodiment, display module 230 includes a warning indicator 270 that includes a plurality of lights and configured to illuminate the lights based on a status of hose appliance and/or the fire-fighting device. For example, warning indicator 270 may illuminate the “EVAC WARN” light when there is an issue with the fluid supply and/or an evacuation warning has been issued, the “WATER LOW” light when there is a conflict between the fluid supply and the amount of fluid requested, and/or the “NOZZLE READY” light when hose appliance 100, nozzle 180, and/or the components and/or devices coupled to hose appliance 100 and/or nozzle 180 are ready for operation and/or use.

In at least some embodiments, hose appliance 100 and/or nozzle 180 includes at least one sensor (not shown) configured to detect whether inlet 150 and/or outlet 160 is coupled to a hose and/or another hose appliance to facilitate determining when hose appliance 100, nozzle 180, and/or the components and/or devices coupled to hose appliance 100 and/or nozzle 180 are ready for operation and/or use. For example, in one embodiment, control module 210 is incapable of sending signals, but can receive information, until inlet 150 and/or outlet 160 is coupled to a hose and/or another hose appliance.

Moreover, in the exemplary embodiment, hose appliance 100 and/or nozzle 180 includes an identifier (not shown) configured to uniquely identify hose appliance 100 and/or nozzle 180. In the exemplary embodiment, the identifier may be any suitable identifying mechanism including, without limitation, a static address, a serial number, a radio-frequency identification (RFID) tag, and/or a bar code. In the exemplary embodiment, the identifier may be embedded in hose appliance 100 and/or nozzle 180 and/or may be coupled to hose appliance 100 and/or nozzle 180 using any suitable coupling mechanism including, without limitation, a band, a collar, a staple, and the like.

In the exemplary embodiment, the sensor and/or identifier 290 may be used to code hose appliance 100 and/or nozzle 180 to a portion of the fire-fighting device. For example, when the sensor detects the identifier and/or identifies that hose appliance 100 and/or nozzle 180 is attempting to connect to a portion of the fire-fighting device, control module 210 addresses and/or assigns hose appliance 100 and/or nozzle 180 to a discharge, logic address, router, or valve controller associated with the portion of the fire-fighting device. In the exemplary embodiment, hose appliance 100 and/or nozzle 180 remain coded to the assigned portion at least until it is disconnected from the hose line. Accordingly, in the exemplary embodiment, the sensor and/or identifier facilitates providing safety measures and may prevent a user from accidentally operating a wrong hose line, mismatching control module 210 to the discharges, and/or asking for fluid before hose appliance 100 and/or nozzle 180 is properly coupled to a hose and/or another hose appliance.

The system can be utilized in several ways. In one embodiment, a fire crew could bring up a pack containing a stand pipe box that includes hose appliance 100 and/or nozzle 180 and a repeater system. Hose appliance 100 and/or nozzle 180 may be coded to the stand pipe box and/or to a discharge at the fire-fighting device. Once connected, the portable stand-pipe box serves as a repeater capable of transmitting a powerful signal. For example, hose appliance 100 and/or nozzle 180 may send/receive information from the stand pipe box, and/or the stand pipe box can act as a repeater for hose appliance 100 and/or nozzle 180 and boost the signal to the fire truck. The stand pipe system can send a signal (e.g., opening and/or closing a valve, increasing and/or decreasing a fluid pressure, and/or increasing and/or decreasing a flow rate) to a logic controller on the fire truck. The stand-pipe box can be set to a floor or crew to send water usage information back to the truck or control module 210. It can also be used to activate nozzle location beacons, evacuation warnings, water tank levels, hydrant capacity and so forth.

In another embodiment the same system could be hardwired in the building and have repeaters located throughout the building. The attack crew could take a standard stand-pipe kit with hose appliance 100 and/or nozzle 180. Hose appliance 100 and/or nozzle 180 may be coded to a stand pipe box that is pre-installed on every floor. This system could then have its own control module 210 which would communicate through repeater boxes on the outside of the building. These repeater boxes could be located anywhere on the exterior of the building. The system could also just serve as a repeater system for hose appliance 100 and/or nozzle 180, and hose appliance 100 and/or nozzle 180 may be coded directly to a valve control system on the truck or a logic system on the truck to control the flow of water to the stand-pipe of the building. In this same system the floors may be coded, or hose appliance 100 and/or nozzle 180 may have floor selections to indicate the crew's position in the building and send the same information to command or the truck operator.

Another way for control of the truck can be achieved by mounting the firefighter control directly to the gated wye. A firefighter could demand water or control the valve on the truck and then manually open and close the valves on the wye as he wishes. This system could then utilize standard nozzles. The gated wye control version would allow for use on stand pipe systems, or hose lays on the ground. The wye would simply have to be coded to that discharge in any fashion. This would also work for ground monitors, long hose lays into larger structures requiring custom hose lays, multiple hand lines controlled from a single discharge at a distant point. In this embodiment, the same control enabled gated wye could act as the repeater for a control enabled nozzle as well and boost the signal to the truck.

In the exemplary embodiment, control module 210 may be configured to account for the tools and equipment on a fire truck. For example, control module 210 may be coupled to a plurality of sensors (not shown) that, when a compartment door is opened or closed, automatically scan and compare identifiers to a previous scan. If there is a variance in the current scan and the previous scan on a per compartment basis, control module 210 notifies the user of the variance. For example, the system may identify that a hose appliance 100 and/or nozzle 180 is missing. In the exemplary embodiment, the sensors may be located near or on a discharge at the fire-fighting device, near a discharge valve controller, or any other convenient place on the fire-fighting device and/or be appropriately labeled. In one embodiment, each sensor is configured to uniquely identify a respective part or portion of the fire-fighting device (e.g., a discharge) and is communicatively coupled to a computer readable form of memory by any suitable communication system.

Moreover, in the exemplary embodiment, control module 210 may be configured to easily customize the vehicle. The fire-fighting device could be stocked and then asked to scan. This state could be set for the standard of the vehicle and this would be the standard for a daily check. This daily check could then be printed or uploaded. This check would provide a more accurate and standardized method of reporting for daily check procedures. These daily check procedures are important for protecting a fire department from liability issues should a problem arise on scene due to lack of equipment. This same system by scanning the compartment automatically when a door is opened and then comparing it again to when the door is closed will help keep tools from being lost or left on scene. This same system can be activated by the truck being put in park and then drive, being placed in or out of pump operations, or any other change in state of the operation of the vehicle which would mark a point in time which the vehicle may have had tools taken off of the truck. The cost of fire rescue equipment is very high. Any system that would keep tools from being lost at scene would have great value to the fire service. This same benefit is important when a truck may be called from one scene to the next. A vehicle may be operating on scene and then have to leave to the next. If the vehicle leaves without a tool and this tool is needed for the next scene the firefighters could be at a serious disadvantage. This same system could also be implemented for an ambulance, heavy rescue truck, or any other truck containing tools and equipment for the rescue field.

For equipment that requires fuel, oil, or any type of material to be at a state of operational readiness can have a mount or holder made to be placed in the truck. This mount or holder can have a scale or sensor placed on, in, or around the device to determine an empty state, less that full state, or full state. This information would then be sent to the same system as described above for accountability of not only that tool but its state of readiness. This type of mounting device would work some of but not limited to the following examples: ventilation fans, chain saws, extrication pumps, circular saws, EMS bags, EMS monitors, EMS monitor bags. Equipment requiring any liquid for lubrication or fuel could also have an internal level sensor which would also communicate with the accountability system by either connection or wirelessly. Battery level checks of anything operated electrically can also be relayed to the system. Items such as flashlights, EMS monitors, suction equipment, laryngoscope handles, radios, thermal imagers, and other devices requiring batteries can also be fitted or modified to work with this system. The charging mechanisms can relay this information or be done by the items themselves.

This system can be modified by the users on a regular basis. Tools could either have a set identifier for the type of tool or the tool could have a number set to it by the department. The tools could be tagged by department, by truck, by tool, or by compartment. It could also include any combination of the previous information. This identifier would then respond to a master system which could also be programmed with the same appropriate information that would best fit the user's needs. This system would then report any changes, discrepancies, or omissions when appropriate or as described above.

This system would comprise of one or more scanners as need per the vehicle and its compartment configuration and equipment load. The scanners would be set to scan the areas and report to a central controller on the truck which can report or notify any information required at the time. This system is automatic based on the parameters of the user or a preset parameter established by the manufacturer of the vehicle or the accountability system. The system could also comprise of tools with some type of identifier to work with the system. This identifier would be manufactured into the equipment or placed externally by the users or manufactures. The system could be wired into the vehicles transmission, compartment door sensors, lights, or pump control system to detect a state in which the system would be required to scan. This allows the functions to be performed without intervention from an operator. The system could also have a display or indicator of some type to notify the users of missing equipment or a piece of equipment that is not in a state of readiness as described above. Sensors, scales, proximity switches and any other device can be located in a mount for a specific piece of equipment and can be wired (or wireless) to send information as that that tools accountability or state of readiness. This system is not limited to fire trucks but has equal use in any apparatus operating in an emergency environment. It could be used on vehicles such as but no limited to tow trucks, police cars, ambulances, heavy rescues, rescue boats. Emergency trailers such as hazardous materials, heavy rescue, trench rescue, decontamination, and many other types of trailers made to carry a large amount of tools to an emergency could also use this technology.
